250W ATX Power Supply

The KHACHIMO GW-ATX250SDA is a 250W ATX switching power supply built for modern standby compatibility. It delivers 80 PLUS Gold efficiency for lower power draw and reduced heat. A resonant LLC topology with DC-to-DC conversion provides clean power and enables efficient sleep states.

Builders who value silent, efficient operation

This unit suits compact or low-power systems where quiet running matters. Zero RPM fan mode stops the fan at low and medium loads for near-silent operation. It is not for builds that need higher wattage for discrete graphics cards or heavy overclocking.

80 PLUS Gold certified efficiency

The Gold rating confirms high efficiency across typical loads, cutting waste heat and fan noise. Modern standby support allows extremely fast wake-from-sleep times. Resonant LLC with DC-to-DC conversion reduces coil whine and keeps voltage stable.

この商品に関する質問

What ATX form-factor space does this 250W PSU require inside the case?

It fits a standard ATX power-supply bay and uses the usual four rear mounting screws.

Which motherboard power connectors must be attached during installation, and which one is often missed?

Connect the 24-pin ATX main plug and the 4+4-pin CPU plug; the CPU plug is the one builders most frequently forget.

When should the internal fan be cleaned to keep the Zero RPM mode working?

Clean the fan and heatsink fins whenever dust is visible on the intake grill; a clogged fan cannot spin down at low load.
